Any new DNS zones (domains) that are added within Orbit are queued
to be loaded into our DNS server at 11pm CST. Changes to an existing
zone(domain) that is already loaded into our DNS servers will be
immediate, but the zones update on a 4 hour ttl. These time frames are for
our local DNS servers only. DNS servers outside of our network may
require more time to see new/changed zones, usually 24 - 48hours.
